TASK DEFINITION: In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
PROBLEM: passage: Not all functions have inverse functions. In order for a function f: X → Y to have an inverse, it must have the property that for every y in Y there must be one, and only one x in X so that f(x) = y. This property ensures that a function g: Y → X will exist having the necessary relationship with f.
 question: if a function is not one to one does it have an inverse?

SOLUTION: No

PROBLEM: passage: Following this string of expansions, 2014 opened with two major departures through mergers. First, Brazilian carrier TAM Airlines merged with LAN Airlines to become LATAM Airlines Group, leaving the alliance without a presence in the world's fifth-largest country. Next, US Airways completed its merger with American Airlines and also left the alliance. Both parent companies stayed with Oneworld. On 24 June, though, the alliance finally approved Air India which joined on 11 July, leaving the alliance at 27 members, where it stands today.
 question: is american airlines part of the star alliance group?

SOLUTION: No

PROBLEM: passage: Rarely, a sharply tilted uterus is due to a disease such as endometriosis, an infection or prior surgery. Although this may make it more challenging for the sperm to reach the egg, conception can still occur. A tipped uterus will usually right itself during the 10th to 12th week of pregnancy. Rarely (1 in 3000 to 8000 pregnancies) a tipped uterus will cause painful and difficult urination, and can cause severe urinary retention. Treatment for this condition (called ``incarcerated uterus'') includes manual anteversion of the uterus, and usually requires intermittent or continuous catheter drainage of the bladder until the problem is rectified or spontaneously resolves by the natural enlargement of the uterus, which brings it out of the tipped position. In addition to manual anteversion and bladder drainage, treatment of urinary retention due to retroverted uterus can require the use of a pessary, or even surgery, but often is as simple as having the pregnant mother sleep on her stomach for a day or two, to allow the retroverted uterus to move forward.
 question: can a uterus change from retroverted to anteverted?

SOLUTION:
Yes
